This option is incompatible with .Fl o . .It Fl M Extract values associated with the name list from the specified core instead of the default .Pa /dev/kmem . .It Fl N Extract the name list from the specified system instead of the default .Pa /boot/kernel/kernel . .It Fl o Report statistics for the old NFS client and/or server. Without this option statistics for the new NFS client and/or server will be reported. .It Fl s Only display server side statistics. .It Fl W Use wide format with interval short summary. This option is especially useful when combined with .Fl c or .Fl s and a time delay. .It Fl w Display a shorter summary of .Tn NFS activity for both the client and server at .Ar wait second intervals. .It Fl z Reset statistics after displaying them. .El .Sh FILES .Bl -tag -width ".Pa /boot/kernel/kernel" -compact .It Pa /boot/kernel/kernel default kernel namelist .It Pa /dev/kmem default memory file .El .Sh SEE ALSO .Xr fstat 1 , .Xr netstat 1 , .Xr ps 1 , .Xr systat 1 , .Xr sysctl 3 , .Xr iostat 8 , .Xr nfsdumpstate 8 , .Xr pstat 8 , .Xr vmstat 8 .Sh HISTORY The .Nm command appeared in .Bx 4.4 .
